    Title 430 – National Soil Survey Handbook Part 629 – Glossary of Landform and Geologic Terms Subpart A – General Information 629.0 Definition and Purpose This glossary provides the NCSS soil survey program, soil scientists, and natural resource specialists with landform, geologic, and related terms and their definitions to— (1) Improve soil landscape description with a standard, single source landform and geologic glossary. (2) Enhance geomorphic content and clarity of soil map unit descriptions by use of accurate, defined terms. (3) Establish consistent geomorphic term usage in soil science and the National Cooperative Soil Survey (NCSS). (4) Provide standard geomorphic definitions for databases and soil survey technical publications. (5) Train soil scientists and related professionals in soils as landscape and geomorphic entities. 629.1 Responsibilities This glossary serves as the official NCSS reference for landform, geologic, and related terms. The staff of the National Soil Survey Center, located in Lincoln, NE, is responsible for maintaining and updating this glossary. Soil Science Division staff and NCSS participants are encouraged to propose additions and changes to the glossary for use in pedon descriptions, soil map unit descriptions, and soil survey publications. The Glossary of Geology (GG, 2005) serves as a major source for many glossary terms. The American Geologic Institute (AGI) granted the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service) permission (in letters dated September 11, 1985, and September 22, 1993) to use existing definitions. Sources of, and modifications to, original definitions are explained immediately below. 629.2 Definitions A. Reference Codes Sources from which definitions were taken, whole or in part, are identified by a code (e.g., GG) following each definition.

While any effort to improve communication in sci- entific research and writing is to be encouraged, we are also concerned that fundamental differences between date and duration, in the way that our profession expresses geological time, would be lost in such an oversimplified terminology. In addition, no precise value for ‘year’ in the SI base unit of second has been accepted by the international bodies. Under any circumstances, however, it remains the fact that geologi- cal dates – as points in time – are not relevant to the SI.

  • Federal Guidelines for Dam Safety, Glossary of Terms, April 2004
    Federal Guidelines for Dam Safety Glossary of Terms April 2004 FEDERAL GUIDELINES FOR DAM SAFETY: GLOSSARY OF TERMS REVISED 2003 Prepared by the Interagency Committee on Dam Safety U.S. Department of Homeland Security Federal Emergency Management Agency Glossary of Terms for Dam Safety The Interagency Committee on Dam Safety (ICODS) was established to provide the Federal agencies involved in dam safety with the opportunity to coordinate their dam safety activities. One of the goals of ICODS is to provide a common forum for the Federal agencies and State officials to exchange ideas and procedures that are used for dam safety and to provide an efficient mechanism for technology transfer. The purpose of this document is to establish a common Glossary of Terms for Dam Safety for use within and among Federal agencies. The objective was to select terms that would be generic and applicable to all dams, regardless of size, owner, or location. The initial document was published in February 1988. The group that prepared the initial glossary consisted of: Joseph S. Haugh Department of Agriculture Chair Jack Thompson U.S. Army Corps of Engineers James Price Tennessee Valley Authority Jack Brynda Department of the Interior Brian Holtham Department of the Interior Edward C. Pritchett U.S. Army Corps of Engineers The document was updated between 1995-1999 by an ICODS task group consisting of: Arthur H. Walz, Jr. U.S. Army Corps of Engineers Chair Jeng I. Chang U.S Army Corps of Engineers Larry Babich Department of Agriculture Sam Shipman Tennessee Valley Authority Daniel Mahoney Federal Energy Regulatory Commission Michelle Barry Department of Interior This document was further updated and finalized by a NDSRB task group consisting of: Meg Galloway Wisconsin Department of Natural Resources Charles Pearre U.

  • Engineering Geology Field Manual
    Chapter 1 INTRODUCTION This manual provides guidelines and instructions for performing and documenting field work. The manual is a ready reference for anyone engaged in field-oriented engineering geology or geotechnical engineering. The manual is written for general engineering geology use as well as to meet Reclamation needs. The application of geology to solving engineering problems is emphasized, rather than academic or other aspects of geology. The manual provides guidance for: • Geologic classification and description of rock and rock discontinuities • Engineering classification and description of soil and surficial deposits • Application of standard indexes, descriptors, and terminology • Geologic mapping, sampling, testing, and performing discontinuity surveys • Exploratory drilling • Soil and rock logging • Acquisition of groundwater data • Core logging • Soil logging • Investigation of hazardous waste sites FIELD MANUAL Although the methods described in this manual are appropriate for most situations, complex sites, conditions, or design needs may require modification or expansion of the suggestions, criteria, and indices to fit specific requirements. Many of the chapters in this manual will always need revision because they cover material that changes as technology changes. Critical comments, especially sug- gestions for improvement, are welcome from all users, not just the Bureau of Reclamation. The appendix contains abbreviations and acronyms commonly used in engineering geology. 2 Chapter 2 GEOLOGIC TERMINOLOGY AND CLASSIFICATIONS

  • Glossary of Geologic Terms
    Glossary of Geologic Terms All definitions are modified from the Glossary of Geology provided online by the American Geological Institute http://www.agiweb.org/pubs/glossary/index.html Acadian Orogeny A middle Paleozoic tectonic event, especially in the northern Appalachians; it is named for Acadia, the old French name for the Canadian Maritime Provinces. The climax of the orogeny can be dated stratigraphically as early in the Late Devonian, but deformational, plutonic, and metamorphic events occurred over a more extended period. The Acadian is a consequence of convergent-margin tectonism and collision of exotic terranes with the eastern margin of North America. For example, the Avalon platform probably docked with Laurentia during the Acadian. andalusite (an-da-lu’-site) A brown to red, orthorhombic mineral: Al2SiO5. Andalusite occurs in thick, elongate prisms in schists, gneisses, and hornfelses; it forms at medium temperatures and pressures of a regionally metamorphosed sequence and is characteristic of contact-metamorphosed argillaceous rocks. anticline (an’-ti-cline) A fold, generally convex upward, whose core contains the stratigraphically older rocks. Ant: syncline. Avalon The Avalon plate is a microcontinent that was sutured to eastern North America during the Devonian-age Acadian orogeny. Indications of the event, represented by radiometric dates ranging from slightly earlier to later, occur in accreted terranes along the southeastern edge of the Appalachian orogenic belt, and in rocks beneath the sediments of the Atlantic Coastal Plain as far southwest as Florida. It was named for the Avalon Peninsula, southeastern Newfoundland. axial surface A surface that connects the hinge lines of the strata in a fold.
